Technical Field

The utility model relates to the technical field of orthodontic appliances, in particular to an axial inclination direction adjustable correcting device.

Background

Currently, orthodontists generally treat patients with teeth or faces with orthodontic appliances, such as brackets, buccal tubes, etc., for example, aiming at the problems of crowding, bucking, uneven tooth arrangement, malocclusion, etc. During conventional orthodontic treatment, an orthodontist attaches a bracket or buccal tube to the surface of a patient's teeth and places an archwire into the archwire slot of the bracket through which the archwire applies corrective forces to the teeth to move the teeth into the correct position. Orthodontic appliances are typically made of metal and are applied to the teeth to affect aesthetics, so some patients choose to apply orthodontic appliances to the lingual side of the teeth for aesthetic purposes during treatment.

The related terms labial, lingual, mesial, distal, occlusal and gingival are industry terms for orthodontic treatment. Taking a certain tooth of the upper jaw as an example, the surface of the tooth may be roughly divided into six faces. The surface of the tooth which is occluded with the mandibular tooth is an occlusal surface; the face of the tooth to which the attached gingival tissue is attached is the gingival face; the occlusal surface is opposite to the gingival surface, and the direction in which the occlusal surface is formed is also called the gingival-jaw direction. The face of the tooth facing the lip is a labial face, the face of the tooth facing the tongue is a lingual face, the labial face and the lingual face are opposed to each other, and a direction in which the labial face and the lingual face are formed is also called a labial-lingual direction. The two surfaces of the tooth which are in contact with the adjacent tooth are a mesial surface and a distal surface, respectively, which are different in that the distance from the middle is far and near, and the direction in which the two surfaces are formed is also called a mesial-distal direction or a mesial-distal direction.

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

In the present utility model, unless expressly stated or limited otherwise, a first feature "up" or "down" a second feature may be the first and second features in direct contact, or the first and second features in indirect contact via an intervening medium. Moreover, a first feature being "above," "over" and "on" a second feature may be a first feature being directly above or obliquely above the second feature, or simply indicating that the first feature is level higher than the second feature. The first feature being "under", "below" and "beneath" the second feature may be the first feature being directly under or obliquely below the second feature, or simply indicating that the first feature is less level than the second feature.

It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.
